Title:
【発明の名称】炭化水素クラッキングとメタンカップリングとを組合わせたオレフィンプロセス
Document Type and Number:
Japanese Patent JPH06506482
Kind Code:
A
Abstract:
An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen for the methane coupling process can provide refrigerant nitrogen to liquify one or more of methane, ethylene and propylene which can be used in the cryogenic separation of the C2+ hydrocarbon products in the cracking process effluent.
